Answer:
12
Step-by-step explanation:
You can solve this problem by setting up an equation.
7 more that double a number is just 2x + 7
Five less than triple that number is just 3x - 5
Since they are equal to each other, you can set them equally to each other.
2x + 7 = 3x - 5
Solve.
7 + 5 = 3x - 2x
x = 12
